Rung 4:0
Resets the hole count sequencers each time that the low preset is
reached. The low preset has been set to zero to cause an interrupt to
occur each time that a reset occurs. The low preset is reached anytime
that a reset C5:0 or hardware reset occurs. This ensures that the
first preset value is loaded into the high-speed counter at each entry
into the REM Run mode and each time that the external reset signal is
activated.
